Every corner of the Crane & Mountain Tunnel offers something new to discover. Lift the crane and the top of the mountain off and place it on the track for dual funtionality. In addition to the multi-storey railway passage and the majestic crane on top, four different sounds activate when the train is passing throught the mountain. This is a treasure trove of fun - and you might even find some gold! Requires 2 AA batteries (not included). Brio was founded in 1884 and Brio Trains have been a classic since 1958. 3+ years.
